Those look neat!
I actually prefer them over the original phat, as they're more colorful (but those right and left buttons would have to go!)

I do. I'm not sure if the dimensions are the same or not but the flip panel looks a little slimmer, and the texture of the plastic looks quite sleek and a little less Fisher-Price! I like the L/R buttons though, don't look so much like they'd pop out of place if you dropped it. I really like the stylus they're using as well.

Quoted from DarkUli:

Thank god they decided on a new model for the Phat.

Those look horrible! I mean freakin' HORRIBLE!

I like them, they look alot sleeker for some reason. The plastic looks alot nicer.

Almost all nintendo protos look bad. When a Proto Ultra 64 controller leaked it looked weird, the one who had it said it was hand made, off balance and with all the buttons without the names on them. Also on the 'net there is a cartridge based GC that was used for development purposes along with the NR reader (dev GC, but using minidvds instead). The cartridge one looks horrible imo.
